Product Name: Vtg 12kgf Child's Expansion Bracelet BellaVance and Sons, & a Locket best Necklace
Vintage 12kgf Child's Expansion Bracelet by BellaVance & Sons, and a goldtone Locket Necklace neither tested Expansion Bracelet is Child's size, engraved with a B on the heart, and stamped 1/20 12kgf Front and BellaVance & Sons. Locket Necklace is a heart Locket, I do not see a mark though I assume 12kgf too, on a 13 inch chain with 1/20 12kgf stamped spring ring. Both items are gold color. Locket has been lined with a blue material and I have not attempted removal. These are coming to you as they came to me. As a set. I best received them very recently. Would be happy to have them find a forever home. Box not included.
